Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 5, a special jig for welding a battery cover includes:

the feeding mechanism 1 is used for feeding nuts 7 and comprises a first feeding plate 9 and a second feeding plate 10 which are symmetrically arranged on a workbench 8, and feeding channels 11 for arranging and discharging the nuts 7 in sequence are arranged in the first feeding plate 9 and the second feeding plate 10;

the clamping mechanism 2 is used for clamping and locking the battery cover 12 and comprises a chuck 13, a plurality of clamping jaws 14 arranged on the chuck 13 and a poking rod switch 15 for realizing locking or unlocking of the clamping jaws 14;

the positioning mechanism 3 is used for rotating the battery cover 12 to a welding position and comprises a rotating disc 16, the chuck 16 is positioned on the rotating disc 16, and the rotating disc 16 is connected with a rotating motor 17;

the operation mechanism 4 is used for conveying the nut 7 into the battery cover 12, and comprises a linear module 18, a support block 19 arranged on the linear module 18 and two pneumatic suction heads 20 arranged on the support block 19, wherein sensors are arranged in the pneumatic suction heads 20;

the linear translation mechanism 5 is used for switching a plurality of welding positions on the battery cover 12 and comprises a linear translation cylinder 21 connected with the chuck 13;

the welding mechanism 6, which is used for welding the nut 7 and the battery cover 12, comprises a laser welding head 22.

The mechanism comprises the following operation steps:

1) the battery cover 12 is manually placed in the chuck 13, and then the lever switch 15 is pulled to drive the plurality of claws 14 to clamp the battery cover 12.

2) At the same time the pneumatic tip 20 is moved by the linear module 18 to the position of the output end of the feed channel 11 to pick up and move the nut 7 to the welding position.

3) The rotating motor 17 is used for driving the rotating disc 16 to rotate, so that the rotating disc 16 is used for driving the chuck 13 to rotate, the position (welding hole 30) of the battery cover 12 on the chuck 13, which needs to be welded, is located right below the pneumatic suction head 20, and the rotating motor 17 stops working when the pneumatic suction head 20 senses the position (welding hole 30) of the battery cover 12, which needs to be welded, due to the fact that the sensor is arranged in the pneumatic suction head 20.

4) The laser welding head 22 is operated to complete the welding of the nut 7 to the weld hole 30.

5) The pneumatic suction head 20 continues the steps 1) and 2) to carry out the feeding work of the nut 7.

6) Since the two welding holes 30 are formed on the battery covers 12, the position (welding hole 30) where the other battery cover 12 needs to be welded is driven to be right below the pneumatic suction head 20 by linearly translating the cylinder 21.

7) The laser welding head 22 is operated to complete the welding of the nut 7 to the other weld hole 30.

8) The above steps are repeated.
